2020 Map of Simeonof Island D-1 SW

USGS Topo · Published 2020

About this map

Pacific Ocean waters dominate this maritime survey of the Aleutians East region, reflecting the isolated character of Alaska’s southwestern archipelago. The map focuses primarily on the seafloor topography of the Shumagin Bank, a submerged feature critical to the underwater landscape of the Gulf of Alaska. While the northern edge of the sheet captures the rugged southern coastline of a landmass in the Simeonof Island vicinity, the majority of the quadrangle is dedicated to mapping the open sea and its bathymetric context. The transition from the shallow shelf of the bank into deeper oceanic waters illustrates the complex marine environment that supports the region's remote ecosystem.
